as it turns out, those would be the least of paul duncsak's problems. something far more sinister was waiting for him inside that million-dollar home in the safe new jersey burbs. >> the theory the police developed is that the killer is on the stairs. and the first shot is up. >> paul duncsak had been ambushed and killed in his own home. the shooter had escaped, and now friends of paul were wondering seriously if they might be next. >> i didn't know if i was on some type of hit list. >> how had paul duncsak's abbreviated life ended in murder? well, you need to understand the marriage. he met his bride-to-be stacey in 1998 at a pharmaceutical conference. he did consulting for the industry, she was a sales rep. friends say they were instantly mad about each other. paul's brother john didn't know what to make of her. she was nothing if not direct.
